A plane takes off and climbs steadily for 15 minutes until it reaches 30,000 feet. It travels at that altitude for 2 hours until it begins to takes 15 minutes at a constant rate. The graph provided below shows the plane's flight.
Height (feet)
000 OE
Time (hours)
a. Identify whether the graph is discrete or continuous
b. Determine the domain and range.
c. Identify key features of the graph (intervals of increase, decrease, and constants) and interpret them in the context of the situation,

Now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.

Can somebody 1. what is the formula for finding the vertical distance between two points on a coordinate plane?

The graph of f(x) = |x| is transformed to g(x) = |x + 11| - 7. on which interval is the function decreasing?
